I like to camp somewhere near a water source, as there's nothing like the sound of a river to wake you in the morning. Any business (cooking, peeing, etc..) is taken care of away from the water, besides sleeping and admiring the beauty:

As for using what nature provides, I like to camp where there's deadwood that lends itself to a nice warm fire.
